Q: What is the location and common issue with the EGA valve?
A: The EGA valve is found on the intake manifold and in most cases, a problem in the emissions system results from a stuck or corroded EGA valve. Feel underneath the valve and push on the diaphragm to confirm its status with the engine cold to keep yourself from getting burnt. The membrane should be maneuverable using moderate pressure. In case it does not move at all or moves with great difficulty, change the EGA valve to a new one. Whenever you are uncertain about its condition, compare this free movement with that of a new valve.
